Abstract
A reflector consists of a ceramic material (2) with a low surface weight, which is applied to the surface (4) of a preformed ceramic front plate (1), and monolithically connected to it. The ceramic material consists of a C/SiC foam. The front plate also consists of C/SiC and has raised and/or depressed areas.
